Thanks

// subfileWidget.js
/***
* This creates a useful method that allows you to retrieve

document.getElementsByClassName = function(cl) {
//create an empty array.
var retnode = [];
//Create a regular expression for searching
//for the classname that was passed in.
var myclass = new RegExp('\\b'+cl+'\\b');
//gets a list of all of the elements on the page.
var elem = this.getElementsByTagName('*');
//Loop through all the elements and check for the
//passed in class name.
for (var i = 0; i < elem.length; i++) {
var classes = elem[i].className;
//Use the regular expression to check the class name.
if (myclass.test(classes)) {
//add the element that matches to the array that gets returned.
retnode.push(elem[i]);
}
}
return retnode;
};

//We will be overriding the existing body.onload method with some of
//our own code. We want to be sure to execute the existing onload code
//so we save a reference to the old onload method in document.body.oldOnload.

//Define the new document.body.onload.
document.body.onload = function (){
//if the oldOnload exists, execute it.
if(document.body.oldOnload){
document.body.oldOnload();
}
//call the initSubfileWidget Method.
initSubfileWidget();
};
